摘要:
A silver halide color photographic light-sensitive material comprises a support and at least one light-sensitive layer. This layer has a plurality of silver halide emulsion layers substantially identical in color sensitivity, but differing in speed. The light-sensitive layer is comprised substantially of monodispersed silver halide emulsions A and B, each containing silver halide particles of the core/shell-type. The silver halide particle sizes of emulsions B and A have a ratio, when multiplied by 100, of less than 70 and the silver halide particles of emulsion B have a silver iodide content in their core that is not less than 5 mole % smaller than that of the core of the silver halide particles of emulsion A.
